Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs)

NIOSH is committed to applying the best available science in dose reconstructions. In keeping with this commitment, completed cases with probabilities of causation less than 50% are reviewed as relevant new information becomes available. The results of these reviews are described in a Program Evaluation Report (PER). The PER details the effect, if any, of the new information on the completed dose reconstruction. If it appears that the compensability of a completed dose reconstruction may be effected, NIOSH is committed to working with the Department of Labor to reopen and rework the dose reconstruction, as appropriate. A Program Evaluation Plan (PEP) describes plans for evaluating specific program details or issues.

• PER 11: K-25 TBD and TIB Revisions
  PDF 17 KB (2 pages)
  
  Document Number: OCAS-PER-0011 Rev-00
  
  About this Document: New document to determine which previously completed claims require a new dose reconstruction as a result of changes to the K-25 dose reconstruction methods.
  
  Approved: September 26, 2007
  
  Summary: There were 432 claims completed by NIOSH between 11/24/2004 and 8/31/2006 that resulted in a POC less than 50%. This does not include claims that may have been submitted in that time frame but subsequently returned to NIOSH for any reason. All these claims will be reviewed by NIOSH to determine if external co-worker data was used. NIOSH will request that DOL return those claims completed before 5/21/2005 determined to have been completed using external co-worker data. NIOSH will also request the return of those claims completed with external co-worker data between 5/21/2005 and 8/31/2006 if they are deemed a Construction Trades worker. DOL will be provided with documentation for the remaining claims indicating the claim did not meet these criteria.

Worker Outreach Activities

Based on a recommendation from the Advisory Board to provide workers and site experts with opportunities to participate in developing the technical documents used in dose reconstruction, NIOSH established a Worker Outreach Program.

At Worker Outreach Meetings, current and former DOE and AWE employees have opportunities to obtain information about Site Profiles, Technical Basis Documents, and Technical Information Bulletins, and to provide information for consideration and possible use in dose reconstruction. This process is valuable to ensure that the technical documents used in dose reconstruction contain correct and useful information.

Below are the Worker Outreach Activities for the K-25 Site:

• April 6, 2005
  Meeting with PACE Local 5-288 and International Unions
  
  Final Minutes
  PDF 45 KB (10 pages)
  
  
• April 5, 2005
  Meeting with Security, Police, and Fire Professionals of America; International Guards Union of America
  
  Final Minutes

Special Exposure Cohort Petition Information for K-25 Site

• Submissions Not Qualifying for Evaluation
  In addition to the petition listed below, two additional submissions were received but did not qualify for evaluation because the class defined in the submission was already included in the SEC.
  
  
• Class Added to the SEC
  
  • Gaseous Diffusion Plants--employees who worked at least 250 days before February 1, 1992, at a gaseous diffusion plant in Paducah, Kentucky; Portsmouth, Ohio; or Oak Ridge, Tennessee and who were or could have been monitored in those jobs using dosimetry badges
    
    Note: The SEC was established by The Act. The K-25 Site was one of the classes that Congress included when The Act was signed.
